Yes handing over KYC which information about yourself is a contentious issue. However you do not expect bounty managers to go through same processes like you because they are already known and it's for that very reason they are handling the project coordination and management instead of you .
However I understand your pains as a fellow bounty hunter. Invariably it's left for you to do such projects or not.
KYC checking bounty managers will not solve any problems for bounty hunters. In many cases, this is the same hired worker. Even if the ICO bounty manager is a member of the ICO team, he can pass through the KYC test as many of us go through - providing not his own data and not his personal document. It would be better if such a check will be carried out by the ICO team, and even better if their documents are checked by the relevant government authorities during registration at the ICO location.
